Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor are within the protection scope of the utility model.

[0028] Figure 1 is a structure schematic view of the material buffering device in the embodiment of the utility model; Figure 2 is a side view of the material buffering device in the embodiment of the utility model.

[0029] As Figure 1 and Figure 2 shown, the material buffering device 100 of the embodiment is arranged between the computer multi-head packaging scale 200 and the packaging machine 300, including transition chute 10, material buffering pipe 20, pneumatic door opening mechanism 30.

[0030] Specifically, the computer multi-head packaging scale 200 weighs the material and outputs the corresponding material, and has a strong discharge outlet 201 in the case of abnormality and a material outlet 202 in the normal working state. The computer multi-head packaging scale 200 is a prior art and will not be specifically described here. The packaging machine 300 is used to receive the material output by the computer multi-head packaging scale 200 and perform corresponding packaging. The packaging machine 300 is a prior art and will not be specifically described here.

[0031] The transition chute 10 has a feeding end 11 and a discharging end 12. The feeding end 11 is connected with the material outlet 202 of the computer multi-head packaging scale 200 in the normal working state.

[0032] In this embodiment, the caliber of the transition chute 10 gradually decreases in the direction from the feeding end 11 to the discharging end 12. The material transmission through the gradually narrowed transition chute 10 can reduce the impact force when the material leaves the transition chute and reduce the material breakage rate.

[0033] The material buffer pipe 20 has a feeding pipe opening 21 and a discharging pipe opening 22. The feeding pipe opening 21 is connected with the discharging end 12, and the discharging pipe opening 22 is arranged at the packaging inlet 301 of the packaging machine 300.

[0034] The pneumatic door opening mechanism 30 includes a bin door 31 arranged at the discharging pipe opening 22 in an openable and closable manner, and a cylinder assembly for controlling the opening and closing of the bin door 31.

[0035] Specifically, when the cylinder assembly controls the bin door 31 to be closed, the material falling in the computer multi-head packaging scale 200 is buffered in the material buffer pipe 20 and the transition chute 10. When the cylinder assembly controls the bin door 31 to be opened, the material will flow out of the discharging pipe opening 22 and be directly input into the packaging inlet 301, effectively reducing the conveying distance of the material to be packaged into the packaging machine, and reducing the material conveying time.

[0036] At the same time, during the weighing and packaging process, the computer multi-head packaging scale 200 does not need to wait for the packaging machine 300 to complete the packaging before re-feeding, and the packaging machine 300 also does not need to wait for the material to be re-input for a long time. The material can be quickly and continuously and stably supplied to the packaging machine 300, so that the production rhythm of feeding and packaging is matched, and the overall operation efficiency of weighing and packaging is effectively improved.

[0037] Reference Figures 3-5 The cylinder assembly includes a cylinder mounting seat 32 and an ear seat cylinder 33.

[0038] The cylinder mounting seat 32 is arranged on the material buffer pipe 20. One end of the ear seat cylinder 33 is provided with an ear seat 331, and the ear seat 331 is rotationally connected with the cylinder mounting seat 32 through a rotating shaft 34.

[0039] Specifically, the ear seat 331 is in a U-shaped structure, and through holes are formed on both sides of the U-shaped structure. The cylinder mounting seat 32 has a cylinder connecting end, and a connecting hole is formed in the cylinder connecting end. The cylinder connecting end is arranged in the ear seat 331 in the U-shaped structure, and the rotating shaft 34 is arranged through the through holes on both sides of the ear seat 331 and the connecting hole of the cylinder connecting end, so that the ear seat 331 is rotatably arranged in the cylinder mounting seat 32, and the ear seat cylinder 33 can rotate around the rotating shaft 34.

[0040] In the embodiment, the rotating shaft 34 is further provided with a bolt hole at both ends, and the position of the rotating shaft 34 can be fixed by arranging a bolt 341, so that the rotating shaft 34 is prevented from falling off. Meanwhile, the bolt 341 is arranged on both sides of the ear seat 331, and the ear seat 331 is limited, so that the ear seat 331 is prevented from deviating.

[0041] Reference Figures 3-5 The other end of the ear seat cylinder 33 is a piston rod 332, and the piston rod 332 is connected with the bin door 31.

[0042] The piston rod 332 is further connected with a fish-eye joint 333, and the bin door 31 is further fixedly provided with a connecting rod 314. The connecting rod 314 has a joint connecting end, and the joint connecting end is rotatably connected with the fish-eye joint 333 through a first rotating connecting piece.

[0043] Specifically, the joint connecting end of the connecting rod 314 is in a U-shaped structure, and through holes are formed on both sides of the U-shaped structure. One end of the fish-eye joint 333 is connected with the piston rod 332, and the other end is provided with a circular ring. The circular ring of the fish-eye joint 333 is arranged in the joint connecting end of the connecting rod 314 in the U-shaped structure, and the through holes on both sides are aligned with the circular ring.

[0044] Further, the first rotating connecting piece includes a first screw rod 334 and a first nut 335. The first screw rod 334 is arranged through the through holes on both sides of the joint connecting end and the circular ring of the fish-eye joint 333, and is fixed through the first nut 335, so that the joint connecting end is rotatably connected with the fish-eye joint 333, and the connecting rod 314 is rotatably connected with the fish-eye joint 333.

[0045] In some embodiments, the first rotating connecting piece can also use a rotating connecting structure such as a rotating shaft, so that the connecting rod 314 is rotatably connected with the fish-eye joint 333.

[0046] When the piston rod 332 drives the fish-eye joint 333 to stretch and retract, the connecting rod 314 rotates around the first screw rod 334, so as to drive the bin door 31 to move close to or away from the discharge pipe opening 22. Meanwhile, a rotatable spherical bearing is arranged in the circular ring of the fish-eye joint 333, which can eliminate the eccentric load in the process of driving the bin door 31 to rotate by the piston rod 332 stretching and retracting.

[0047] Reference Figures 3-5The material buffering device 100 further comprises a door mounting seat 23 arranged on the material buffering pipe 20, and the door 31 is provided with a mounting end 311 extending from the door 31 and rotatably connected to the door mounting seat 23 through a second rotating connecting member.

The mounting end 311 is provided with a mounting hole, and the mounting end 311 is arranged between the two side plates and the through holes on the two side plates are aligned with the mounting hole.

[0049] Further, the second rotating connecting member comprises a second screw 312 and a second nut 313. The second screw 312 is arranged through the two through holes of the door mounting seat 23 and the mounting hole of the mounting end 311 and is fixed by the second nut 313, so that the mounting end 311 is rotatably arranged in the door mounting seat 23, and the door 31 can rotate around the second screw 312.

[0050] In some embodiments, the second rotating connecting member can also use a rotating connecting structure such as a rotating shaft, so that the door 31 can be rotatably connected to the door mounting seat 23.

[0051] In the embodiment, during the extension and retraction of the piston rod 332 to drive the rotation of the door 31, the connecting rod 314 rotates correspondingly, and the fish-eye joint 333 can effectively eliminate the eccentric load. At the same time, the lug seat cylinder 33 can rotate correspondingly, further reducing the eccentric load during operation, and the rotation of the door 31 can be more stable to open and close or close.

[0052] Reference Figures 3-5 The door 31 is matched with the shape and size of the discharge pipe opening 22, and can tightly close the discharge pipe opening 22 when the door 31 is opened and closed, so as to prevent the buffered material from leaking out.

[0053] Specifically, the discharge pipe opening 22 is an oval inclined surface, and the door 31 is an oval. The discharge pipe opening 22 is arranged as an inclined surface. When the door 31 is closed, it can be tilted and tightly closed on the discharge pipe opening 22 along the inclined surface to prevent the buffered material from leaking out. When the door 31 is opened, the material can be discharged first at the tip of the inclined surface, so that the material can be quickly discharged, effectively avoiding material accumulation and blockage, and further improving the overall operation efficiency.

[0054] The working process of the material buffering device 100 in the embodiment is as follows:

[0055] When the packaging machine 300 has not finished packaging, the piston rod 332 of the ear seat cylinder 33 is kept extended so that the door 31 is kept close to the discharge port 22, the computer multi-head packaging scale 200 keeps normal weighing and discharging, the material is sent out from the material outlet 202, is transported through the transition chute 10 and is buffered in the material buffer pipe 20.

[0056] When the packaging machine 300 finishes packaging and needs to discharge again, the piston rod 332 of the ear seat cylinder 33 is retracted to drive the fish eye joint 333 to move upwards, correspondingly drive the connecting rod 314 to rotate and move upwards, thereby drive the door 31 to rotate in the direction away from the discharge port 22, the door 31 is opened, and the material buffered in the material buffer pipe 20 is directly input into the packaging inlet 301 of the packaging machine 300 from the discharge port 22.

[0057] After the discharging is completed, the piston rod 332 of the ear seat cylinder 33 is extended to drive the fish eye joint 333 to move downwards, correspondingly drive the connecting rod 314 to rotate and move downwards, thereby drive the door 31 to rotate in the direction close to the discharge port 22, so that the door 31 is close to the discharge port 22 to continue buffering the material input by the computer multi-head packaging scale 200, and the door 31 is opened again when the next packaging is performed.

[0058] The above is only a preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
